Georgia school shooting: New details on weapon revealed

State investigators are revealing new details about the gun a 14-year-old boy allegedly used to kill two teachers and two students at his Georgia high school.

Colt Gray allegedly brought the AR-15-style rifle used in last week’s shooting — a Christmas gift from his father, according to sources — to school alone, the Georgia Bureau of Investigation said Thursday. The long gun “could not be disassembled,” so the teen hid it in his backpack, the GBI said.

On the morning of the shooting, Gray asked his teacher for permission to go to the school office and speak to an unidentified person, the GBI said. The teacher allowed him to leave and take his belongings with him, the GBI said.

The 14-year-old then went to the bathroom and hid from the teachers, then later allegedly pulled out the rifle and began shooting, according to the GBI.

Colt Gray is accused of killing four people and wounding nine others at Apalachee High School on September 4.

Seven of the nine people injured were shot and wounded, the GBI said Thursday.

Colt Gray is charged with four counts of murder. Additional charges will be pursued, prosecutors said.

The teen’s father, Colin Gray, is charged with four counts of involuntary manslaughter, two counts of second-degree manslaughter and eight counts of cruelty to children, the GBI said. He is accused of knowingly allowing his son to possess the gun used in the shooting, according to the GBI.

Investigators believe Colt Gray received the AR-style weapon used in the shooting as a Christmas gift from his father, sources said.

Colt Gray and Colin Gray both made their initial court appearances Friday. Neither entered a plea and both are scheduled to return to court on Dec. 4.
